Check your regulator/rectifier output is it according to standard.
Is your battery in prime condition as a minimal caopacity battery retention will make the alternator/charger produce a higher output level to quickly charge the battery to optimal state.
Good enough?

My battery mush have shorted out causeing my speedo to jump back and forth it blew a fuse the low beam and the tail light, now when trying to start it will hardly run and will not rev up.

That is a sign that the voltage regulator is going out or already has. You can test with a volatge meter by starting the bike up and see what the voltage reads at an adle and then at approx 2000 rpm. at an idle it should read 12.75 - 13.50 volts and when reved up it should read 13.50- 14.00 volts.

if it raeds 12.50+ at idle and does not raise up then your voltage regulator is undercharging and will need to be replaced. If it reads over over 15.00 volts at any time then it is overcharging and thats usually when headlights blow and main fuses. Must replace the voltage reulator.

100% sure that is what your problem is and i hope you get her fixed and back on the road soon
Good Luck and Best Regards

Any issues with after market batteries? thanks Bob

Check the voltage with a volt meter with the cycle running should be 14.5 volts or less preferably 14 volts. If it is higher check or replace the voltage regulator. I just replaced mine on a Yamaha 1100 V Star 2002.

2002 V Star 1100 voltage problems

oh yes..........
voltage regulator.... this unit also contains the rectifier which changes generator electricty from AC to DC for the battery. test the volt reg and it may be ok for the volts, but if the rectifier part is knackered, it will completely screw up every battery, they will not take AC !!!! every time I get a bike in for repair with volt reg. probs I always put in a new battery

Charging problem battery is overcharging

Hi and welcome to FixYa,

Almost always, overcharging would indicate a faulty voltage regulator or more specifically, shorted.  A shorted condition would not adjust to the need/status of the battery but supply to the battery an always maximum charging current, hence the overcharging.

On most versions, the voltage regulator would be behind the cover below the battery.

Good luck and thank you for asking FixYa.
